Sirui Saturn RF50B-A 50mm
At just 465g, the carbon fiber build makes this the lightest full-frame 1.6x anamorphic, delivering a 2.4:1 or wider 2.8:1 aspect ratio with a T2.9 aperture and 10-blade diaphragm for oval bokeh. Its compact size mounts on gimbals and FPV drones for unique overhead perspectives, and optional blue or natural flare coatings add stylistic control. This manual-focus lens suits solo filmmakers and drone operators prioritizing a portable, cinematic look without heavy rigging.
